Pito is a set of C++0x header libraries to facilitate writing system call interceptor libraries based on LD_PRELOAD wrappers. The program "pito" is also provided for loading Unix commands with such wrappers. This system is capable of passing command line arguments to loaded plugins for easy configuration. Pito is supplied with a powerful system call sandbox library to prevent modifications to supplied filesystem locations and a system call logging library.

SVL (System Call Virtualisation Layer) is a C++ library that can be used to detect, abort, and rewrite system calls. The possible uses include, but are not limited to, studying the system call trace of a program; sandboxing a program to tighten security; or selectively rerouting system calls, such as file operations, to different paths or even different sytems to create distributed architectures. SVL allows you to change the low level constructs for system call invocation by allowing you access to both the registers and the target program's memory. As well as having the low level access, SVL has high level classes for dealing with the major syscall operation types.
